Description

Tilting Table

The present invention relates to a tilting table for processing a workpiece for rotating the workpiece in the vertical direction according to the position of the machining surface by rotating the table on which the workpiece is fixed. The present invention relates to a tilting table for processing a workpiece which can freely adjust a rotation range of the work piece as necessary by simply changing the number or position of engagement of the table by configuring a plurality of tables coupled to rotate in the vertical direction. .

In general, in the case of processing the workpiece by using a machine tool in an industrial site, a method of performing the necessary processing by operating various processing heads in a state where the workpiece is firmly fixed to the working table is mainly used.

However, in the case of the processing head is generally performed to perform the required machining while lifting or moving in the vertical direction and the horizontal direction perpendicular to the ground on which the working table is supported when the processing surface of the workpiece is formed at various angles at various locations The workability is deteriorated because it is inevitable to release the workpiece fixed to the working table and then fix the work piece so that the required processing surface faces the processing head and then fix the work piece again to the working table. There was a problem that time increases.

In order to solve this problem, recently, the working table to which the work is fixed is configured to be rotated at an angle in the vertical direction so that the table can be rotated within the range in which the table can be rotated even if the work is not released. By tilting, a tilting table capable of being adjusted so that different processing surfaces of the workpiece can face the machining head has been developed. Details of the tilting table are described in detail in the following [1].

However, in the case of the tilting table according to the following [Document 1], because the rotation angle of the table installed so as to be rotatable in the vertical direction on the base supported on the ground is only about 30 ° clockwise or counterclockwise, respectively, the workpiece In the case where the machining surface is formed at various positions and angles over the entire surface, it still has the problem that it is inevitable to readjust the fixed state of the workpiece as in the prior art, and the problem is that the workpiece is a V-shaped cylinder block (or V-shaped). Such as an engine block, which is more weighted in the case of large volume and weight.

It is to provide a tilting table for processing a workpiece that can be easily machined.

In order to achieve the above object, a tilting table for processing a workpiece according to the present invention includes a first table on which a workpiece is placed, and at least one second table on which the workpiece is placed and detachably coupled to the first table. A base for supporting them in the lower part of the first and second tables, and a rotating means for rotating the first and second tables on the base to rotate the workpiece according to the position of the working surface. The two tables are coupled to one side or both sides of the first table so as to rotate with the same trajectory as the first table, thereby increasing the rotation range of the workpiece.

In addition, the first and second tables have a lower surface having an arc-shaped curved surface, and the upper surface of the base on which the first and second tables are installed is a curved surface corresponding to the lower surface of the first and second tables. The first and second tables are rotated in a manner in which a lower surface slides along an upper surface of the base, respectively.

Further, the first and second tables are coupled such that the lower surfaces of the tables adjacent to each other form an arc, and the lower surfaces of the tables adjacent to each other are slid continuously along the upper surface of the base. It is characterized by increasing the rotation range.

The apparatus may further include a plate-shaped connecting member which is commonly coupled to an outer surface of a table adjacent to each other among the first and second tables.

In addition, the outer surface of the table adjacent to each other and the inner surface of the connecting member in contact with each other is characterized in that the assembly grooves and the assembly projections of the corresponding shape for guiding the position and the angle to each other is formed.

lower surfaces

12 and 22 of the first and second tables 10 and 20 described above. It consists of a curved surface (that is, an arc shaped curved surface).

On the other hand, the rotating means 40 is the first and second tables (10, 20) up and down the ground so that the workpiece (C) can be rotated according to the position or angle of the machining surface formed on the workpiece (C) To rotate in the direction, whereby the workpiece C can be rotated such that any workpiece can be positioned in an easy-to-machine position (i.e., a position opposite to the machining head).

To this end, in the present embodiment, the rotating means 40 is configured as shown in FIG. 2 as an example. In FIG. 2, the rotating means 40 rotates the first table 10 for convenience of description. The same is true even when the pivot means 40 rotates the assembly of the first and second tables 10 and 20.

In addition, in the specification and claims of the present invention, the first table 10 refers to a table that is coupled to the pivoting means 40 by way of example, and the second table 20 refers to a first table. It refers to a table that is interlocked with the first table 10 in a state coupled to (10).

In addition, in the present invention, the case where only one rotation means 40 is installed as an example will be described, but is not limited thereto and may be provided in plurality, if necessary.

As shown in FIG. 2, the rotation means 40 includes a drive motor 41 capable of forward and reverse rotation, and a pinion gear 42 that is rotated by the drive motor 41. On the

lower surfaces

12 and 22 of each of the two tables 10 and 20, an arcuate rack gear 13 meshes with the pinion gear 42 to rotate the first and second tables 10 and 20. By forming the first and second tables (10, 20) coupled in the forward and reverse rotation of the pinion gear 42 is configured to rotate in conjunction with each other as will be described later.

At this time, the rotation means 40 is preferably installed so as not to interfere with the rotation of the first and second tables 10 and 20. For this purpose, the driving motor 41 is an example of the base 30 in this embodiment. It is installed on one side of the first and second table (10, 20) to be spaced apart from the lower surface (12, 22) of the first and second table (10, 20) does not interfere with the drive shaft 43 having a diameter By the pinion gear 42 is configured to be connected.

In the present embodiment, as an example, the first and second tables 10 and 20 are rotated by the rack-pinion, but the present invention is not limited thereto, and the rotation means 40 is a worm hill-worm gear within the range of performing the same function. It may be preferably implemented in any one of a variety of ways, such as known.

In addition, the first and second tables 10 and 20 or the second table 20 may be coupled to be adjacent to each other by the connecting member 50. In this case, the coupling position and the coupling angle are always kept constant. The outer surface of the table (10, 20) and the inner surface of the connecting member 50 in contact with each other so as to guide the assembly groove 25 and the assembly protrusion of the shape corresponding to each other for guiding the position and the angle to each other ( More preferably, 55) is formed.

In this embodiment, the case in which the connecting member 50 is commonly coupled to one side of the neighboring table has been described as an example, but is not limited thereto, and may be naturally coupled to both sides of the table as necessary.

In addition, the connection member 50 may be coupled to the table by a variety of fastening means, such as bolts / nuts, screws, clamps within the range performing the same function.

According to the above configuration, the first table 10 and the second table 20 slide in the circumferential direction along the upper surface 31 of the base 30, and the vertical direction of the ground on which the base 30 is supported. (Ie, clockwise or counterclockwise).

In this case, the second table 20 is coupled to one side or both sides of the first table 10 to rotate with the same trajectory as the first table 10. Specifically, the first and second tables 10 and 20 ) Are combined such that the

lower surfaces

12, 22 of neighboring tables form one arc.

Therefore, the tilting table for processing the workpiece according to the present invention can be freely increased the rotation range of the workpiece to more than 360 ° according to the number of engagement and the position of engagement of the second table 20 as described below. In this case, the

lower surfaces

12 and 22 of the neighboring tables are continuously slid along the upper surface 31 of the base 30 to increase the rotation range of the workpiece. .

FIG. 3A is a diagram for exemplarily describing an actual apparatus configuration when the workpiece C is placed on the tilting table 1 according to the present invention shown in FIG. 1, and the workpiece C will be described below. As shown in FIG. 3B, a description will be made based on the case of the V-shaped cylinder block.

As shown in FIG. 3A, when the workpiece C is placed on the tilting table 1 according to the present invention, at least one auxiliary table (or length) may be used depending on the size (or length) of the workpiece C. 2, 3) may be further installed, the auxiliary table (2, 3) may be configured to rotate the table by the same angle in dependence on the rotation of the tilting table (1) according to the present invention without a separate rotation means .

On the other hand, in the case where the workpiece C is a V-shaped cylinder block as shown in FIG. 3B, the entire machining surface is the upper surface f1, two upper inclined surfaces f2 and f3 adjacent to the upper surface, and adjacent to each upper inclined surface. A total of ten surfaces should be machined, including two lower inclined surfaces f4 and f5, two sides f6 and f7 adjacent to each lower inclined surface, a bottom surface f8 and a front and rear surface f9 and f10.

However, the tilting table according to the prior art is limited to the angle of rotation of the table as described above, so if the cylinder block is placed on the table once, even if the front and rear surfaces are processed with a 90-degree machining head, up to five surfaces (f1, f2, f3) Since only f9 and f10 may be processed, there is a problem in that the position where the cylinder block is placed on the table must be readjusted several times in order to process the entire surface.

On the other hand, in the case of the tilting table 1 according to the present invention, the cylinder block can be freely rotated more than 360 degrees depending on the position of the machining surface by the combination of the first and second tables 10 and 20. By simply raising the first cylinder block, there is an advantage that the entire machining surface can be processed by the coupling and rotation of the first and second tables 10 and 20.

Hereinafter, a detailed assembly method and operation of the tilting table according to the present invention for processing the entire surface of the cylinder block will be described in detail with reference to FIG.

As shown in Fig. 4A, when the cylinder block, which is the first workpiece C, is raised so that the bottom surface is placed on the upper surface of the first table 10, the upper surface f1 processing and the 90 degree processing head The front and rear surfaces f9 and f10 can be used, and the machining of the upper inclined surfaces f2 and f3 uses the second table 20 as the first table 10 as shown in FIGS. ) And then rotate the first and second tables 10 and 20 in a clockwise or counterclockwise direction.

At this time, the support means (S) shown in the drawing is a conventional support means for stably fixing the workpiece (C) to the first and second tables (10, 20).

Next, machining of both sides f6 and f7 is possible by rotating the first and second tables 10 and 20, as shown in Figs. 4C and 4F, and the lower inclined surfaces f4 and f5. ) Can be processed by rotating the first and second tables 10 and 20 as shown in Figs. 4D and 4G.

At this time, the second table 20, which is located in the upper part by the rotation of the second table 20 coupled to both sides of the first table 10 in Figure 4 (d) to prevent interference with the machining head It is preferable to dismantle and remove the connection member 50 after the rotation is completed.

In addition, in FIG. 4G, the second table 20, which is positioned at the upper side by rotation of the second table 20 continuously coupled to one side of the first table 10, also interferes with the machining head. It is preferable to dismantle and remove the connecting member 50 after the rotation is completed to prevent.

Finally, the bottom surface f8 can be machined by rotating the first and second tables 10 and 20, as shown in Fig. 4H.

As described above, in the tilting table 1 according to the present invention, the first table 10 and the at least one second table 20 on which the workpiece C is placed rotate on the same trajectory on the base 30. Since the configuration is coupled so as to change the number of the second table 20 or the coupling position coupled to the first table 10 by adjusting the rotation range of the workpiece (C) more than 360 ° freely if necessary There is an advantage that it can.

Therefore, the tilting table 1 according to the present invention has the first table (C) once even when the workpiece C is large and the machining surface is formed at various positions and angles, like the V-shaped cylinder block. 10) Alternatively, simply mounting on the first and second tables 10 and 20 has the advantage that the entire required working surface can be easily processed without readjusting the position on which the workpiece C is placed.

The present invention can be applied to a tilting table for rotating the workpiece according to the angle of the workpiece in a fixed state when machining the workpiece using a machine tool in an industrial field, in particular, such as V-shaped cylinder block It is useful in the case of the large size and the processing surface formed at various positions and angles.
